The Antonov An-2 is
a Soviet mass-produced single-engine biplane
utility / agricultural aircraft designed and
manufactured by the Antonov Design
Bureau beginning in 1946. Its remarkable
durability, high lifting power, and ability
to take off and land from poor runways have
given it a long service life. The An-2 was
produced up to 2001 and remains in service
with military and civilian operators around
the world.
The An-2 was designed as a utility aircraft
for use in forestry and agriculture.
However, the basic airframe is highly
adaptable and numerous variants of the type
have been developed; these include
hopper-equipped versions for crop-dusting,
scientific versions for atmospheric
sampling, water-bombers for fighting
forest-fires, flying ambulances,
float-equipped seaplane versions and lightly
armed combat versions for
dropping paratroops.
The most common
version is the An-2T 12-seater
passenger aircraft. All versions (other than
the An-3) are powered by a 750 kW (1,010 hp)
nine-cylinder Shvetsov ASh-62 radial engine,
which was developed from the Wright
R-1820. The An-2 typically consumes 2.5
litres (0.55 imp gal; 0.66 US gal) of fuel
per minute.
